This book was released on 2013-06 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semi-empirical force-limited vibration method was developed and implemented for payload testing to limit the structural impedance mismatch (high force) that occurs during shaker vibration testing. The method has since been extended for use in analytical models. The Space Communications and Navigation Testbed (SCAN Testbed), known at NASA Glenn Research Center (GRC) as, the Communications, Navigation, and Networking re-Configurable Testbed (CoNNeCT) project utilized force-limited testing and analysis following the semi-empirical approach. This presentation presents the steps in performing a force-limited analysis and then compares the results to test data recovered during the CoNNeCT force-limited random vibration qualification test that took place at NASA Glenn Research Center (GRC) in the Structural Dynamics Laboratory (SDL) December 19, 2010 - January 7, 2011. A compilation of lessons learned and considerations for future force-limited tests is also included.

This book was released on 2018-06-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibration tests were performed to develop and validate the forced limited vibration testing capability at the NASA Langley Research Center. The force limited vibration test technique has been utilized at the Jet Propulsion Laboratory and other NASA centers to provide more realistic vibration test environments for aerospace flight hardware. In standard random vibration tests, the payload is mounted to a rigid fixture and the interface acceleration is controlled to a specified level based on a conservative estimate of the expected flight environment. In force limited vibration tests, both the acceleration and force are controlled at the mounting interface to compensate for differences between the flexible flight mounting and rigid test fixture. This minimizes the over test at the payload natural frequencies and results in more realistic forces being transmitted at the mounting interface. Force and acceleration response data was provided by NASA Goddard Space Flight Center for a test article that was flown in 1998 on a Black Brant sounding rocket. The measured flight interface acceleration data was used as the reference acceleration spectrum. Using this acceleration spectrum, three analytical methods were used to estimate the force limits. Standard random and force limited vibration tests were performed and the results are compared with the flight data. Rice, Chad and Buehrle, Ralph D.

Book Synopsis Analytical and Experimental Investigation of Overtesting During Assembly-level Shock Testing by : Jean-Philippe Deblois
Download or read book Analytical and Experimental Investigation of Overtesting During Assembly-level Shock Testing written by Jean-Philippe Deblois and published by . This book was released on 2009 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical shocks induced by the detonation of pyrotechnics ordnances are known to be highly detrimental to the integrity of spacecraft components. As a result, it is desirable to qualify these components as early as possible to prevent failures during launch. Assembly-level shock tests are usually performed on these components. However, these tests are suspected to be the cause of several failures that would not occur during flight. The knowledge acquired in vibration testing suggests that the overtesting is mainly due to the rigidity of the mounting interface between the component and the testing device. Consequently, the test configuration lacks the dynamic absorber effect which should naturally occur in flight configuration. While the Force Limited Vibration (FLV) technique has been developed to reduce the overtesting occurring in vibration testing, no systematic methodology have been proposed to measure and to reduce the shock overtesting to this date. The objective of this study is to conduct systematic analytical and experimental sensitivity investigation on the overtesting occurring in the assembly-level shock testing. A reconfigurable prototype of an electronic box and a mounting structure have been designed and modeled using the finite element method. The prototype is then fabricated and tested to demonstrate the occurrence of overtesting experimentally. The vibration overtesting and the C 2 coefficients of the semi-empirical method are evaluated using FLV technique. The shock overtesting is evaluated similarly using an acceleration excitation generated for the shaker test. The results show that no significant correlation between the vibration and the shock overtesting exist. Finally, a method to reduce the shock overtesting is proposed in which the shock specification is notched at the main frequencies to limit the response of the structure.
